Multi-resolution sampling designs nest fine-scale sampling within information about broad-scale processes that may affect finer-scale data. These designs are very appropriate for studies seeking to detect the effects of processes operating over a variety of scales. We tested the utility of a novel, low-intensity/ cost, multi-resolution sampling design in an investigation of the relationship between the suspension-feeding pinnid bivalve <i>Atrina zelandica</i> and surrounding benthic macrofauna. Interactions were modelled at different spatial scales, and a variety of covariates were included in the search for the best statistical and most sensible ecological model. We chose our sampling sites to encompass broad-scale gradients in <i>A. zelandica</i> density and size, depth, sediment characteristics and hydro-dynamics. We found these gradients helped explain the relationship between <i>A. zelandica</i> and associated benthic macrofauna. Our results suggest that the strength of effects of <i>A. zelandica</i> on benthic macrofauna was dependent on 2 aspects of spatial scale: grain (the area over which <i>A. zelandica</i> measurements were made) and lag (the distance between where the <i>A. zelandica</i> and the macro-fauna were sampled). By nesting fine-scale measures of benthic macrofaunal community composition within different spatial arrangements of individual <i>A. zelandica</i>, we were able to determine that the maximum distance between individual <i>A. zelandica</i>, rather than density estimates, better explained effects of <i>A. zelandica</i> on benthic macrofauna. This suggests the value of integrating broad-scale surveys with localised experiments so that organism interactions can be more generally interpreted on the basis of dynamics within landscapes rather than as density-to-density comparisons.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Integrating heterogeneity across spatial scales: interactions between <i>Atrina zelandica</i> and benthic macrofauna","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-23 01:31:50.454849","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2002,"MonPub":null,"DateUpdate":"2003-07-03","DateCreate":"2003-07-03","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000178175000011","VABBcode":null,"OpenAcc":0,"DOI":"10.3354/meps239115"},"refs":null,"anarec":{"AnaID":36127,"PubliDate":2002,"Pagination":"115-128","XtraPublOfAnaID":null,"ISBN":null,"Volume":"239","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43354,"SerRR":"Marine Ecology Progress Series.
